What is EEW?
The Earthquake Early warning (EEW) will give advanced warning to those who will experience a tsunami. All earthquakes produce a series of different types of shock waves, which travel at different speeds and carry different amounts of energy. The fastest shock waves, and the first to arrive, are called P waves. These travel about twice as fast as the next fastest shock waves and rarely cause any damage. The next shock waves to arrive are called Shear waves (or S waves), followed by Love waves and Rayleigh waves, which cause most of the damage by earthquakes. Since the P waves arrive first, they can provide an advance notice of the heavy shaking to follow. The warning time is about 1 second for every 5 miles of distance to the Hypocenter of the earthquake. This amount of warning can give automated systems plenty of time to respond and enough time for people to react. 1. The use of P waves to produce an early warning system has been hampered in the past by two technical problems: how to eliminate false positives (triggering on man-made vibrations); and how to distinguish between small earthquakes (which should be ignored) from large ones. SWS has solved both of these problems. 2.

The December 26, 2004 Indian Ocean tsunami was caused by an earthquake that is thought to have had the energy of 23,000 Hiroshima-type atomic bombs. The epicenter of the 9.0 magnitude quake was under the Indian Ocean near the west coast of the Indonesian island of Sumatra. The violent movement of sections of the Earth’s crusts known as tectonic plates displaced an enormous amount of water, sending powerful shock waves in every direction. The tectonic plates in this area had
